Question

A phlebotomy technician is preparing to obtain a blood specimen from a patient for thyroid studies. The technician should select a collection tube that has a top with which of the following colors ?

A. Speckled
B. Gray
C. Green
D. Light blue

Answer 1

The phlebotomy technician should select a collection tube with a light blue top. Light blue tops are used for tests that require plasma, such as thyroid studies.

Step-by-step explanation:

The phlebotomy technician should select a collection tube with a top that has the color Light blue.

Each color of the collection tube represents a different additive or anticoagulant that is used for specific tests. Light blue tops are typically used for tests that require plasma, such as thyroid studies. The light blue tube contains sodium citrate as an anticoagulant, which prevents blood from clotting.

Using a tube with the correct color is important to ensure accurate test results and prevent interference or contamination.
